Cool Down and Automatic Shut Off
This option consists of an activation button labeled Auto Cool/Shutdown, a relay, and a timed relay.
To enable this feature:
While the unit is currently in operation, push the black button labeled Auto Cool/Shutdown.
The machine will disable heating and start cooling for the preset amount of time. When the time
runs out the machine will shut down.
If needed the machine can still be shut down by pressing the stop button.
A Timed Relay (TDR) mounted inside the machine’s electrical enclosure controls the amount of time
the machine cools before shutting down. Rotating the dial on the front of the TDR can change the
amount of time. The factory-preset time limit is 5 minutes; the adjustable range of the TDR is from
zero to ten minutes.
Adjusting Auto Cool Down/Shutdown Timer
(Factory Default Set for 5 Minutes, Adjustable from 0 to 10 Minutes)
Turn off machine.
Locate the timer on the electrical subpanel.
Refer to panel layout drawing for the particular machine, located in the door pocket. The
Timer will be designated as auto cool/shutdown time delay relay.
Turn adjustment dial on timer clockwise to increase time and counter-clockwise to decrease
time.
To determine the proper setting. Heat the machine up to operating temperature. Once you
reach operating temperature, turn the set point down to the lowest setting. Start timing the
cool down period; as soon as the unit reaches a temperature below 125F you can stop
timing. The time you have recorded is where you want to set the auto cool timer to.
6.8
Emergency Stop
The emergency stop device will shut the machine down regardless of the operating mode. Once the
emergency stop device has been activated, it must be disengaged by turning the button clockwise.
Disengaging the emergency stop will not restart the machinery but only permit restarting.
Per the risk assessment of the machine, the emergency stop is not wired to a safety rated
relay.
Do not wire additional safety components to the Mokon stop relay or modification of the
emergency stop circuit is prohibited.
6.9
Valved Process Bypass
This option is simply a direct fluid path between the “TO” process line and the “FROM” process line
that will allow you to bypass your process partially or completely via a metered globe valve on the
outside back of the unit. This provides a means of controlling the amount of flow out to the
process should you wish to reduce it from the normally full flow condition.
